TYI'EWRITING MACHINE.

Application filed O'ctober 13, 1924-. Serial m 743,199.

To all whom it may concern:

Be it known that I, EDWARD E. BARNEY, citizen of the United States, andresident of New Rochelle, in the county of Westchester and State of NewYork, have invented certain new and useful Improvements in TypewritingMachines, of which the following is a specification.

My invention relates to typewriting machines and more particularly tomeans for holding a platen clutch disengaged so that the platen may beturned indefinitely in dependently of the line spacing wheel.

The main object of my invention, generai ly stated, is to provideimproved means of I the character specified which are simpl'erinconstruction, effective in use and may be readily embodied in existingmachines without material modification of the structural featuresthereof.

To theabove and other ends which will hereinafter appear, my inventionconsists in the features of construction, combinations of devices andarrangements of parts hereinafter described and particularlypointed outin the appended claims.

In the accompanying drawings wherein like reference characters indlcatecorrespond ing parts in the different views, Figure 1 is an enlargedfragmentary detail front elevation with parts in section of theleft-hand end portion of a carriage equipped with the device of myinvention.

Figure 2 is a detail fore-and-aft vertical sectional view of the samewith parts omitted, the view being taken on the line 2'2 of Figure 1 andlooking in the direction of the arrow at said line. i c

Figure 3 is a fragmentary top plan view with parts in section showing aportion of the construction disclosed in Figure 1.

Figure 4 is a detail perspective View of the latch and the slide whichsupports it; the parts being shown separated for clearer illustration. Ic

Figure 5 is a detail transverse sectional view taken on the line 5'5 ofFigure 1. and looking in the direction of the arrowat said line. A

Figure 6 is av detail sectional view-taken on the line 66 of Figure .1and looking in the direction of the arrow at said line.

I have shown my invention embodied in the present instance in a No. 5Remington Noiseless machine in which it may be readi as it now exists.

ily incorporated without materially modify ing the structural featuresof said machine It should be understood, however, that the invention isnot restricted to use in such machine but maybe employed in typewr'itingor like machines generally.

The platen 1 is mounted to turn in bean ings in a carriage thatcomprises end plates or brackets 52 united by a bearing rail 3 and otherconnecting rods and devices not shown.

Any suitable clutch maybe employed to connect the line spacin'gwheel 4:and the platen to turn together, and when the clutch is released topermit the platen to be turned independently of said wheel. The clutchshown in the present instance comprises radially disposed pawls 5mounted in radial ways 6 formed in a member, disk or casting" 7,supported in a manner to be hereinafter described and on which the linespacing wheel is loosely mounted. The disk 7 hastapped openings toreceive headed screws 9 by which a plate 10 is secured to the member 7and retains the line spacing wheel in place thereon. The plat'elOiscentrallyapertured and riveted at 11 to a supporting sleeve'12. Thepawls 5, are adapted to move radially in their ways into and out ofengagement with inwardly directed teeth 13 formed on the ring-like linespacing wheel 4. When the. pawls are moved out and engage the teeth 18,the line spacing wheel and platenare clutched to turn together. When thepawls are ithdrawn from the teeth 13, the platen 'is free to be turnedindependently of the line spacing. wheel, which at this time is heldagainstturning movement by-the usual spring pressed roller detent 14.-Anendless contractile spring l5is employed to withdraw the pawls 5 toreleasing position. This spring is received and seated in depressions 16in the outer-faces of the pawls and exerts its power towithdraw allthreepawls. The means whereby the pawls are forced to en: gaging position andwhich enables them, when desired, to be withdrawn to releasing position,comprises three plungers 17 each having a cylindrical cross section atpointsin the length'thereof. These plungers are seated for longitudinalsliding movement'in semi-cylindrical aligned bearing recesses 18 and 19,respectively, in the periphery of a cylindrical spindle 20' and a stud21; The stud 21 is fixedly secured to the casting 7 on which the linespacing wheel is mounted and is also received in a bearing sleeve 22secured to the platen. A pin 23 connects said sleeve and stud and theinner end portion of the sleeve receives a bearing in an opening in theleft-hand end plate 2 of the carriage. The longitudinally movable spindle 20 is received within and surrounded by the sleeve 12, and issupported at its outer end portion in a bearing opening 24 in thedepending arm 25 of a bracket 26. Said bracket is secured to theleft-hand end plate 2 of the carriage frame by screws 27 and 28. Afinger wheel 29 has a hub 30 by which it is secured to the outer end ofthe spindle 20 by a screw 81. The outer end of the sleeve 12 has threeinwardly projecting ears 32 formed thereon and each of which extendsinto a companion bearing recess 18, causing the sleeve 12, (togetherwith the parts connected thereto including the platen), and the spindle20 to turn together, but enabling the spindle to receive an independentlongitudinal movement. Each of the ears 32 also forms a bearing for theouter end of a coiled expansion spring 33. Each of these springssurrounds a reduced stem or pin 34 on the associated plunger 17, andbears at its inner end against the body portion of such plunge and tendsto shift it in. The movement of each plunger under the action of itsspring forces the inclined face on the lunger against a correspondinglyinclined face 36 .on the inner end of the companion pawl 5, therebyforcing the latter out into engagement with the teeth 13 on the linespacing wheel and connecting the latter to turn with the platen. It willbe observed that each plunger 17 has a cut-out 37 therein in which isreceived a ring 38 secured to the inner end of the spindle 20. The outerwall of each cut-out 37, co-acting with the ring 38, under the power ofthe companion spring 33 forces the spindle 20 and the finger wheel 29carried thereby into the clutch engaging position, shown in Figure. 1.Therefore, in the position of the parts shown in this figure the fingerwheel 29 is connected to turn with the platen, as it is at all times,and the line spacing wheel is connected to turn with the platen. hen,however, the finger wheel and spindle 20 are drawn out the plungers 17will be withdrawn, enabling the spring 15 to withdraw the pawls 5 todisengaging position, and enable the platen to be turned by the fingerwheel 29 independently of the linespacing wheel, which at this time isheld against turning movement by the spring pressed roller detent 14.hen the operator releases the finger wheel 29, the parts will bereturned to the Figure 1 position re-engaging the platen clutch. Theparts, as thus far described, are substantially the same as thoseemployed in the No. 5 Remington Noiseless machine and are not of myinvention but are disclosed and claimed in the copending application ofGeorge G. Going, Sr. No. 19,204 filed Mch. 30, 1925.

In accordance with my invention I provide simple and efficient meansco-acting with the construction thus far described to positively latch,lock or hold the clutch disengaged, when it is desired to use themachine indefinitely in this condition for irregular spacing.

I reduce the outer end portion 20 of the spindle 20 where it is receivedin the hub 30 of the finger wheel, thus forming a circumferentialshoulder 39 (see Fig. 1) where the reduced portion of the spindle joinsthe main body portion thereof. This reduced portion 20 is received inand projects through an opening 40 in a depending ear 41 of a slide 42.The construction is such that the inner end of the hub 30 on the fingerwheel co-acts with the outer side of the car 41, whereas, the shoulder39 co-acts with the inner face of said ear. This construction causes theslide to partake of the longitudinal movement of the spindle with fingerwheel, but permits the platen to be rotated independently of the slide.The depending ear or arm 25 on the fixed bracket 26 is pro: vided with ahorizontally disposed guide slot or opening through which the slideprojects, and by which the slide is guided in its rectilinear movementand held against turning movement. Pivoted at 44 .on the upper side andinner end of the slide is a latch,

catch or locking device, indicated as a whole by the reference numeral45. This latch is provided with depending finger pieces 46 on oppositesides thereof thatproject down on opposite sides of the slide 42 andco-act therewith to limit the independent pivotal or lateral movement ofthe latch on the slide. The latch also extends through the guide slot 43in the fixed bracket and is provided with a locking shoulder or engagingportion 47.

- When the latch is in the dotted line position shown in Figure 3, it isineffective to hold the spindle 20 and finger wheel 29 in the drawn-out,clutch-releasing, position. When, however, the latch is shifted to thefull line position in said figure, the shoulder 47 engages the bracketnear one end wall of the slot 43 and prevents a return movement of theslide 42, the spindle 20 and the platen clutch controlled thereby. Theclutch is thus held released without interfering with the turning of theplaten independently of the line spacing wheel by the finger wheel 29.

By the construction and arrangement of the parts which enable the latch45 to slide in and out with the finger wheel 29 and controlling spindle20, the latch is at all times maintained in substantially the samerelation to the finger wheel 29, so that the latch may be readilymanipulated for int cpendent pivotal movement by fingers of the samehand of the operator that grasp the finger Wheel 29, aliording aconvenient means for locking and releasing the latch.

This is a matter of importance in combination with the clutch mechanismdisclosed herein, which was specially devised as a one-hand control atthe left-hand end of the platen, as fully brought out in saidhereinbefore mentioned Going application. It will be observed that inorder to release the clutch a pull'to the left, or in the direction ofthe letter feed movement of the carriage, is exertedonthefinger wheel29. Since this pull is resisted by the carriage escapement mechanismthere is no necessity of holding the carriagewith one hand whilereleasing the clutch with the other, therefore providing a one-handcontrol for shitting the clutch, and also by the present invention forlocking it.

WVhile'the latching means of my inven- 'tion may be readily combinedwiththe platen clutch of a Remington-Noiseless inachine without materiallyaltering the construction of the latter, such means may be embodied inother typewriting machines and may be combined with other forms ofplaten clutches without departing from my. invention as it is defined inthe accompanying claims.

What I claim as new and desire to secure by Letters Patent is y 1.
